Answer: False
Explanation:
By definition, the z-score of the random variable, x, is

where
μ = the population mean
σ = the population standard deviation
Because only the sample mean and the sample standard deviations are known, we cannot calculate the z-score. Instead, we can calculate the Student t-test statistic.

For 7, r=4.1, and for 8, r = 8.7
Step-by-step explanation:
r is the distance from the center point to anywhere in the circle, meaning that (assuming C is the center point), You just take the length of the side from C to the other points in the circle.
